Pontiac & GMT400 Nut
Yes. I know this isn't a vehicle. But it may someday end up in one, if not as a coffee table. So I've always been facinated by building engines, by watching Engine Power on Saturday mornings and now on youtube, and Engine Masters among others. I got good at ripping apart lawnmower engines and never touching them again. So I decided a winter project for me will be to set my ADD ass down and learn how to rebuild an actual engine. I picked up a bunch of stuff from a friend for a smoking deal. Here's what I got:
-1975-1980 400ci SBC fully disassembled. Looks to me mostly there, needs bearings, a good clean, a magnaflux, and hopefully just a single ball hone and ridge ream before I can assemble. The provided crank is already .010 under as indicated by the crank bearings. I'll be interested to see what the bores are, as they are suspiciously clean for the age of the engine. The cylinder head casting numbers indicate they are 1969-1970 350 heads with 76cc combustion chambers, nothing special, but will need to have valve seats done to run on non leaded gas. Unknown aftermarket cam with a date from 2001 stamped on it, unknown stock looking 4 valve spot pistons. Crank does have a double roller gear on it.
- 2000 350 Vortec with I think 200k miles on it. Came from a guys work truck c2500. Fully complete minus harness, this I do know ran and drove. Now for this one, I have a new in box Jegs Vortec carb intake, MSD street Fire HEI dizzy (can be used on the 400) and a set of MSD plug wires. Not sure what head casting they have.
- unknown year 2wd 4l60e.
Plans?
Well if like to get the 400 into a short block. I have been gathering all the required tools to measure and assemble the engines. Also would get a set of junkyard vortec heads for the 400 for the 64cc chambers. I really don't want to split the 350 up for just the heads. This weekend I'm taking alot of parts to go get sonic washed, then I'll need to start measuring.
